SPECIFICATION forming part of Letters Patent No. 514,143, dated February 6, 1894.

Application filed March 27, 1 893- To all whom it may concern.-

Be it known that we, FRANK M. BROOKS and CHARLES J WOLFREYS, citizens of the United States, and residentsof Brooklyn,in the county 5 of Kings and State of New York, have invented certain new and useful Improvements in Gas-Regulators for Gas-Burners, of which the following is a specification.

Our invention relates to an improved reguto lator for gas burners and it consists in the peculiar construction and arrangement of the parts hereinafter described and shown in the drawings hereof.

In the drawings, Figure 1, illustrates an ele- 5- vation of the device partly in section. Fig.2, is a .plan of the adjustable screw plug, viewed from the top. Fig. 3, is a view from below of the perforated plate which supports the valve.

A, is the arm of the gas bracket.

'13, is the vertical nipple upon which the pillar is ordinarily screwed.

O, is the pillar. It may be of any desired construction. a

D, is what we term the regulator section. It has alower interiorly threaded part, E, and an upper exteriorly and interiorly threaded part, F. The part E, is adapted to thread onto the nipple, B, and the part F, is adapted to receive upon its outer side, the pillar C. At about the middle portion of the section D, a partition or diaphragm G, (see Figs. 1 and 3) divides the section into two chambers. The diaphragm G, is perforated with a number of holes, H, and a central hole, I.

J, is the stem of a valve; K, the valve, is simply a flat disk of metal rigidly fastened to the stem J and of such size as to cover the holes H, in the diaphragm G, when resting upon that diaphragm and yet sufficiently small not to touch or rub against the interior walls of the upper section, D. The valve stem is preferably expanded or upset somewhat at its lower end as shown in order that the valve may be confined to the diaghragm, so that it be not lostduring transportation or otherwise. It is a detail of manufacture, however, which is not essential. The stem, J, extends upwardly above the valve disk, K, and

is preferably rounded or partially pointed at Serial No. 467,725. (No model.)

its upper end as shown. This rounding or pointing, however, is likewise a detail of manufacture and is not essential.

L, is what we term the screw plug regulator. It is a piece of metal having a disk at its upper end, which is screw threaded on its periphery, the threads being adapted to mesh into and easily work in the screw threads cut on the interior of the upper chamber of the section D, so that the screw plug regulator can be easily screwed up or down therein. There is a stem, M, extending downwardly from the said disk, which is bored centrally from end to end as at N, andis provided with one or more holes, 0, and the stem, J, of the valve is made of such size and length as that it can be easily slid up and down through the hole, N, and the parts are so adjusted that When the disk, K, of the valve is resting upon the diaphragm, G, the upper and preferably rounded end of the stem, J, will about coincide with the lower end or side of the holes, 0. The point of it, however, may be somewhat above their lower sides, as shown, so that there will be, when the parts are in this position, but little, if any interference with the passage of the gas through the holes, 0, by the stem, J.

The operation is as follows: The gas being turned on, it passes through the openings in 80 the gas fixture, into the lower chamber of the section, D, thence passing upwardly through the openings, H, H, in the diaphragm, G, it lifts the valve, as shown in dotted lines, in Fig. 1, and in so doing the upper part of the stem, J, passes upwardly through the hole, N, in the plug adjuster, L, more or less cutting off the passage of the gas through the holes, 0, in the depending part, M, depending upon the degree of elevation of the valve. Almost immediately after the turning on of the gas, the valve attains a definite position at which it remains until the pressures vary, where-. upon there will be an automatic readjustment 5 It will be seen that the relation between 9 the upper parts of the stem, J, and the gas inlet holes, 0, may be altered so as to secure greater or less cutting off of the flow by screwing the screw plug adjuster farther into or too out from the upper chamber of the section, D, so that the burner can be very easily regulated to burn the desired number of feet per hour, and in order that the screw plug aduster may be more easily manipulated, we provide an ordinary groove, resembling the screw driver groove in the head of a screw shown at P.

Having described our invention, We claim- 1. The combination in agas burner regulator of a section between the fixture and the pillar, which embodies a perforated diaphragm, a hollow plug vertically adjustable in said section, a chamber between the diaphragm and the plug, said plug having holes in its sides within the said chamber, a valve supported upon the diaphragm, and having an upwardly extending stem, which rests partly within the said hollow plug, substantially as set forth.

2. The combination in a gas burner regulator of a section having interior screw threads for engagement with the fixture and exterior screw threads for engagement with the pillar and which embodies a perforated diaphragm, a hollow vertically adjustable plug, a chamber between the diaphragm and the plug, said plug having holes in its sides within the said chamber, a valve supported upon the diaphragm, provided with an upwardly extending stem, which rests partly within said hollow plug, substantially as set forth.

3. The combination in a gas burner regulator of a perforated diaphragm, a superposed plug, a chamber between the plug and the diaphragm, said plug having openings in its sides, which connect with said chamber, a valve supported upon the diaphragm, and having a stem which extends both above and below the valve, the lower part whereof engages with the diaphragm and the upper part whereof enters the hollow plug, substantially as set forth.

4. The combination in a gas burner regulator of a section between the fixture and the pillar having screw threads adapted to engage with them both, a perforated diaphragm, extending across the section, a vertically adjustable plug having a laterally extending flange, the periphery of which is threaded, the threads whereof engage the threads on the interior of the section, a valve supported by the diaphragm and provided with an upwardly extending stem, which enters the said hollow plug, substantially as set forth.

5. In a gas burner regulator, the combination of two diaphragms or partitions, the upper one having a hollow plug, which enters the chamber between the two diaphragms, said plug having an opening in its side within said chamber, a valve which rests upon the lower diaphragm,closing the openings therein, said valvebeing provided with a stem,which, as the valve is elevated, enters said hollow plug, substantially as set forth.

6. The combination in a gas burner regulator of two valves, the lower one operated by a gravity acting valve and the other one located above the first named valve and actuated by the stem of said valve, said upper valve being adjustable toward and from the lower one, whereby the flow through the upper valve can be determined, substantially as set forth.
